Cell throughput achieved with SU-MIMO (left) and MU-MIMO (right), without distributed antennas. Empirical cumulative density functions of the cell throughput obtained with SU-MIMO and MU-MIMO transmission in a cellular network without distributed antennas, and a total of eight transmit antennas. The performance with one, two, or four receive antennas per user is compared. The maximum Doppler frequency equals f
=10 Hz. The SU-MIMO transmission is based on SVD precoding and equalization, or CLSM without antenna subset selection and ZF equalization. The MU-MIMO transmission is based on ZF precoding and MET or QBC antenna combining, with perfect and quantized CSIT.
